A password is only one layer of protection. If someone steals it, they can access your private conversations and your identity. Two-Factor Authentication (2FA) is a second, different lock for your accounts.
Why One Key Isn't Enough
Think of your online security like a high-security vault. Your password is the first door. In a world of data breaches and sophisticated phishing, that first door is often easier to pick than we’d like to admit. 2FA acts as a second vault door—one that requires a completely different kind of key that only you possess.
Even if an attacker discovers your password through a leak or a trick, they remain locked out because they cannot provide the second piece of evidence required to prove your identity.
